You have a place in your XML document type for (e.g. hex-encoded)
BLOBs to be included or referenced.  Each BLOB in turn should be an
encoding of something using one of a delimited set of more-or-less
standard encodings.  You want to allow or require document authors to
signal which encoding they're using.

The standard example is images, where the encodings might be png, svg,
